Firefox users: name your essential extensions

The add-on system of the Firefox web browser is without doubt one of the browser's strongest features. It is superior to what other browsers have to offer as it lets developers do more which in turn resulted in add-ons such as Tree Style Tab, NoScript or Private Tab only being available for the browser and not for others simply because of that.

Firefox's add-on system is going to take several hits in the near future that will affect extensions in several ways.

Firefox's new multi-process system e10s will deliver the first hit as it will render add-ons incompatible. The Are We e10s Yet website shows the status of hundreds of popular add-ons for the web browser of which 124 are listed as compatible, 78 as "shimmed", 109 as broken, and 562 as untested.

firefox add-ons e10s

The overall Firefox add-on count is larger than that which means that the site does not even list all add-ons.

While Mozilla and many add-on developers are working on resolving bugs and issues, it seems like a dead giveaway that a number of add-ons won't be compatible when multi-process is enabled in the browser.

For instance, add-ons that a developer abandoned won't receive updates to make them e10s compatible.

But multi-process Firefox is not the only change the add-on ecosystem has to overcome in the future. Mozilla announced back in August 2015 that it plans to make dramatic changes to Firefox add-ons.

The organization plans to deprecate XPCOM and XUL based add-ons, and introduce a new extension API WebExtensions as well.

Both won't affect the browser this year or the first half of 2016 as Mozilla stated vaguely that it would take at least a year but probably longer than that before the changes would be implemented in Firefox.

The WebExtensions API won't be as powerful as Firefox's current system. Mozilla wants it to be more powerful than Chrome's implementation though by working closely with developers to implement needed functions to the API so that popular extensions remain compatible with Firefox versions that rely on WebExtensions.

The deprecation will break add-ons, there is no doubt about that and it is also likely that it will hinder innovation in add-on development as well as developers will only have access to the API and not the "whole" browser anymore.

Let me start

We have a list of Best Firefox add-ons here on Ghacks which I'd all like to see make the cut. My personal must have add-ons are NoScript, Classic Theme Restorer and Dictionary Switcher.

Now You

Given all that, it is time to create a list of essential Firefox add-ons that should survive multi-process Firefox and the move to WebExtensions.

Feel free to post your favorite Firefox add-ons in the comment section below. I'll analyze the comments and create a list of them all sorted by popularity and post a new article about it. If this gets enough traction, we could even consider delivering the list to Mozilla.

Note: Please don't mention or post links to YouTube downloaders as this is not permitted by Google (the ad provider here on Ghacks).

Update: The results are in.

    I too have several oldies but goodies which utilizing the “about:config” “extensions.checkCompatibilty” boolean which is set to “false” has allowed their usage since Fx3.0 or so. Can not Mozilla allow users to continue this ploy and be happy. I’ve been using Fx since before 2,0 and tried many times Chrome, Opera and others yet I always come back to my beloved Fx. Perhaps this mayhap be an easier solution than permissions for those unsigned, outdated & yet still in use extensions. Think about it… as I’ve always said, : “FTW, Freedom Through Wisdom.”

    NoScript, Adblock+, Ghostery, BetterPrivacy.

    Also, as someone who saves lots of web pages offline (digital graphics tutorials, computer howto pages, recipe and cooking pages, editorials and rant fodder of all kinds, etc.) I have got to have HackTheWeb. It allows deleting all the shite you don’t ever want to see again from a page before you save it. If HackTheWeb doesn’t make the cut then alas neither does FF. I’ll have to find a different browser with equivalent functionality. (Hope I don’t have to. I’ve tried lots of other FF and Chrome add-ons that claim to do the same thing but none do it as effectively and transparently as HTW.)

    My COLD 40 (ten years ago I would thought this was an outragous amount of addons lol)

    1. About Add-ons (v0.7.1-signed) — Adds an About button to extensions, themes, and languages in the Add-ons list.

    Finally sold after 4 days and nights in sub menu hell.

    2. Adblock Edge (v2.1.9.1-signed) — Ads were yesterday!

    For some reason, the original went south.

    3. Adblock Plus Pop-up Addon (v0.9.2.1-signed) — Makes it easy to block pop-ups with Adblock Plus.
    4. Add-ons Manager Context Menu (v0.4.2.1-signed) — Add more items to Add-ons Manager context menu.

    More INFO , cause I love to read.

    5. Add Bookmark Here ² (v23.0.20140225.1-signed) — Add a menuitem “Add Bookmark Here…” to Bookmarks Menu.

    Why this still ain’t part of ff?

    6. Add to Search Bar (v2.7.1-signed) — Add any search on any page to the Search Bar.

    Another… Why ain’t it part of.

    7. AppLauncher (v0.8.7.1-signed) — This extension lets you launch an external application through the context menu.

    Used with my proxysel to fix the extensions.ini by read line and replace method from BATCH FILES.

    8. ChromEdit Plus (v2.9.10) — A User Profile Editor Plus… Open The Chrome, Profile, & Install Folders. Open The File Manager. Restart Application.

    This is needed to edit USerChrome.css for FoxDie Theme.

    9. Cleanest Addon Manager (v7.0.1-signed) — Cleanup your Addon Manager.

    Does clean it up.

    10. Color toggle (v0.16.1-signed) — Toggles the foreground/background/link colors between two values.

    I just needed this. I can’t explain why.

    11. Context Search (v0.6.3.1-signed) — Expands the context menu’s ‘Search for’ item into a list of search engines.

    I LOVE THIS! OMG

    12. customize_titlebar_v2 (v0.7.1-signed) — Customize the browser titlebar

    Vanity Plates… or a way to tell CyberFox, Aurora, Nightly, Pale Moon seperated at a glance.

    13. Disable Auto-update (v1.1) — Disable Auto-update.

    A new theme for 2015 it seems, I only going to dread in the coming months as the security exploits catch up to the unpatched since JULY 2015 Microsoft Boycott because of TRUST death.

    14. Element Hiding Helper for Adblock Plus (v1.3.2.1-signed) — Helps you create element hiding rules for Adblock Plus to fight the text ads.

    For when that UGLY Yellen is on Drudge or Zerohedge

    15. FEBE (v8.3.1-signed) — Backup your Firefox data

    Back Scratcher!

    16. FireFTP (v2.0.19.1-signed) — FTP Client for Mozilla Firefox.

    I love checking out old FTP’s.

    17. FireSSH (v0.94.7.1-signed) — SSH Client for Mozilla Firefox.

    I usually disable this, cause I use other terminals, but I install it for EMERGENCY.

    18. ITEM CENSORED AS PER REQUEST ;o) You must GUESS the name of the I can’t say. Looks like it starts with an “F”, please stop hurting your head thinking about it.

    19. Flip or Rotate Image (v0.9.1-signed) — Adds submenus for flipping or rotating to the image context menu.

    Nothing like it for these weird auctions I go to, when the box lot is a bunch of JUNK and you need to ROTATE to read the text on the boxes.
    Pretend it’s a box of RF connectors, if you rotate the photo you can read the labels easier. Really good for DVD and CD auctions, but also RECORDS, and TAPES or BOOKS even. I really LOVE this extension.

    20. Ghostery (v5.4.7) — Protect your privacy. See who’s tracking your web browsing and block them with Ghostery.
    21. Greasemonkey (v3.4.1) — A User Script Manager for Firefox
    22. More About (v1.2.13) — Adds “about:” menu and button.
    23. Neo Diggler (v1.0.6.1-signed) — A URL manipulation tool for power users
    24. Nightly Tester Tools (v3.7.1-signed) — Useful tools for the nightly tester.
    25. NoScript (v2.6.9.36) — Extra protection for your Firefox: NoScript allows JavaScript, Java (and other plugins) only for trusted domains of your choice (e.g. your home-banking web site). This whitelist based pre-emptive blocking approach prevents exploitation of security vulnerabilities (known and even unknown!) with no loss of functionality… Experts will agree: Firefox is really safer with NoScript :-)
    26. Open Link in New Tab (v0.1.2014070301.1-signed) — Loads links in new tabs, by conditions.

    Frustration finally got this installed. My START page is PHYSICALLY ON MY DRIVE–hand edited from the ORIGINAL TEMPLATE at fravia.org back in the day

    when I CLICK links I want them in NEW TABS, unless I have cookies and scripts and doing ecomerce on a SINGLE PAGE.

    27. Open Profile Folder (v1.3.3.1-signed) — Open current profile folder from “Tools” menu or toolbar button.

    Helps debug glitches and trouble

    28. Profile Folder Button (v1.0.5) — Adds profile folder button.

    Uh huh… yeah,

    29. ProxySel (v1.3.12b) — The Proxy selection and processing utility is a Mozilla extension that let you select a proxy from a drop down menu. You may import proxy lists in different formats, available from http://proxy-list.org/, http://www.checkedproxylists.com/, http://www.proxylists.net/. The normal way to do is to load a file from webpage suggested above and import this file into ®Firefox with ProxySel, test the Proxies and rate it. To use the TOR feature, you have to install TOR from http://tor.eff.org first. Please use Firefox 2 or higher

    note: I won’t give this extension up yet, It still lives in 2015, I made it change ports. by hex editing the port number on it.
    In my opin it should been PART of firefox EARLY ON. Foxyproxy is garbage.

    30. QuickJava (v2.0.5) — Enable/Disable Javascript, Java, Flash, Silverlight, Animated Images, Cookies, Images, CSS, and Proxy from Toolbar.

    ESSENTIAL… The PRIMARY FLIGHT CONTROLS Perhaps this is the ONE that addresses the article the most for me.

    31. Restart (v1.2.7) — Adds “Restart” menu and button.

    Annoying why ain’t it IN FF?

    32. Resurrect Pages (v2.0.6.1-signed) — Resurrect dead pages, by finding their ghosts.

    Love it..

    33. ScrapBook (v1.5.11.1-signed) — Helps you to save Web pages and organize the collection.
    34. ScrapBook CHM Creator (v1.1.6.1-signed) — Windows Compiled Help creator for the Scrapbook extension.

    an electronics tech without these in 2015? Don’t think so.

    35. Scroll To Top (v4.5.1.1-signed) — Scroll to top and vice versa in a window.

    Productivity

    36. Show Profile (v0.9.9.9.1-signed) — Display profile on window title or customized locations (with or without icon)
    37. Status-4-Evar (v2014.07.06.05.1-signed) — Status widgets and progress indicators for Firefox 4+

    Productivity, Sensors, I put the Primary flight controls here for the PLUGINS

    38. Stylish (v2.0.2.1-signed) — Restyle the web with Stylish, a user styles manager.

    clickty clik

    39. User Agent Overrider (v0.2.5.1-signed) — Override browser User-Agent string

    This one holds the string between boots.

    40. User Agent Switcher (v0.7.3.1-signed) — Adds a menu and a toolbar button to switch the user agent of a browser.

    this one has MANY strings to choose from. I may take string from here and use elsewhere for the session or PROBLEM website.

    Security (privacy is security):

    Usability:
    Classic Theme Restorer, Configuration Mania, Menu Wizard, Go Parent Folder, Sort & Search Customization, Tiny Menu,
    Restartless Restart, HackTheWeb, Profilist, Remove It Permanently, All-in-One Sidebar, Close Tabs to the Left,
    Download Status Bar

    Other:

    I tend to shy away from “add-ons that a developer abandoned” and look for other options. I wish it was more obvious at Mozilla addons. Maybe a filter, “updated within last 12 months” or something.

    Absolutely essential, will not upgrade if not supported, caused my to abandon Chrome when Side Tabs was deprecated essential:

    Tree Style Tabs

    Seriously. That’s the big one. The rest are simply nice to have, though I’d be loathe to give up:

    uBlock Origin
    tabPreloader
    Load Tabs Progressively
    Unload Tab
    Youtube Center

    But yeah. No Tree Style Tabs is a no go for me.

    The three I find essential are:-
    uBlock Origin
    uMatrix
    Throbber restored

    Maybe the last needs explanation – I use Autohotkey a lot and often need to know when the active browser tab has stopped loading. I also have a private extension which I wrote to interface with my password manager (us retired it folk need to keep fiddling) but that was fairly straightforward add-on api code, so hopefully it should survive (I guess I should test that)

    I also use many, but a few are life-changing or time-saving:

    * Session Manager: if all other reasons for not using Chrome weren’t significant, this one would still be enough.

    * Xmarks: the best (if not the only) solution for consistent cross-browser bookmarks syncing, a must if you need to use other browsers as well.

    * Multifox: creates independent cookies sections, so that you can be simultaneously logged twice in a same website, like having two different Gmail accounts open, for example.

    * Tab Mix Plus: for managing (surviving!) a ton of tabs: styles, multiple lines, add-tab-button on top left corner, open next to the current one, etc.

    * Open in browser; Save file to; saveLinkOnAltClick: I open a lot of PDF files, and sometimes they are set as “download”, sometimes as “view in browser”, so the first addon gives me back the control when I am being forced to download it instead of just reading it; the second one provides immediate proper-placing solution when downloading something; the third gives me quick multiple files downloading skills (just alt-click each one to automatically download it).

    * Print edit; pdfit: these two addons provide proper exporting solutions, as the first allows you to remove clutter and the second makes a faithful copy of what you are seeing, which almost never happens when you print it as PDF.

    * FoxyProxy: best multiple proxy handling solution I know.

    * url-addon-bar; Star-Button in Urlbar; RSS Feed Icon in Navbar; Pocket (old addon): UI customization for having all tools inside the urlbar (making bookmarks, importing to Pocket, changing proxy profile, etc.)

    [The old Pocket addon is the only one that shows you your queue-list and, most importantly, allows you to edit it by changing title, tags, etc.]

    And, last but not least:

    * Stylish: a single multi-purpose addon, that gives me square tabs, UI colors customization, hides those annoying plugin-activation notifications, hides the private browsing mask when using Private Tab, changes scroll-bars, hides Gmail’s right side column (ads, contact info, etc.), and increases the search-bar size so that it becomes too large for showing alway and gets into a drop-down menu, increasing the urlbar but still staying available for when I want to manage search engines (which I add by activating, using and deactivating the Add to Search Bar addon).

    I have heaps of extensions installed but really there’s probably only one that I actually feel is essential:

    Classic Theme Restorer

    The day they cut the APIs that allow that extension to do what I want with it, which is pretty much revert and/or disable most of the rubbish changes Mozilla has made in the last several years, I’ll have to consider changing browsers, which for me is a horrendous concept since Firefox is very close to my heart regardless of how much Mozilla tries to stab my heart with it.

    I use DownThemAll! (talk about a stupid name), Ghostery, uBlock Origin, HTTPS-Everywhere and Tab Mix Plus. DTA is the least useful for me, but the others are must-haves, Ghostery, uBlock Origin and HTTPS-Everywhere just for security/privacy reasons and Tab Mix Plus because it is just awesome.

    I like your Best Firefox Addons (Add-ons?) page (that’s a ton of work), especially the way that you categorized them. I’m going to replicate that when I do some updating to my site, although, I’ll use id attribute tags on the add-on’s names to jump to the listed previews. I may even link to the reviews that you’ve done for some of the add-ons if that’s okay with you. We share similar styles in how we review and present add-ons, and in all honesty, it would save me a lot of time and work.
    I know that I don’t really need your permission to link to your articles, but I said “if that’s okay with you” because SEO is more important to you and I wouldn’t want to affect it negatively even though I highly doubt that it would.
    My site’s numbers are low, but it ranks well for its specific content and the linking would be of related content.

    You’ve already listed some of the add-ons that I use and consider to be essential, so I’ll just add some that I didn’t see.
    Textarea Cache – Essential for writers.
    https://addons.mozilla.org/firefox/addon/textarea-cache
    “This extension will save automatically the content in textarea or WYSIWYG editor when user is typing. User can recover the saved texts in the cache window, even the tab or the window is closed unexpectedly.”

    * Classic Theme Restorer (tons of options and features)

    * Fireshot – really awesome web page grabber that can easily save an entire page (or portion) to a PDF or JPG/PNG.

    * Gmelius – fantastic Gmail UI overhaul tool

    * Greasemonkey + Hit Hider script – allows me to permanently hide a chosen URL from appearing in Google search results

    * Lastpass – best password mgr, IMO

    * DownThemAll – excellent download mgr

    * Menu Wizard – highly useful Firefox context menu editor

    * Toggle Animated Gifs – I can press F8 to stop all gif animations on a page

    * TinyURL generator – right click on a page and get a shortened URL auto-copied to the clipboard.

    Firefox would be “just another browser” without Tab Mix Plus. Great adjuncts to TMP are All Tabs Helper and Multiple Tab Handler. While those three make using and managing multiple tabs really possible, Session Manager substantially improves on the sessions management components of both FF and TMP, and uBlock Origin provides what I believe is a unique function by allowing blocking of individual elements on a page.

      Chrome doesn’t have powerful extensions:
      beyond australis (autohide url bar, excellent for laptops)
      image toolbar (saving images with a click)
      tab groups helper (easier to work with multiple tabs)
      Noscript (don’t need introduction).

      But nothing is perfect. Not one program, not one OS ( https://www.facebook.com/notes/kevin-frei/your-os-sucks/10153643564654427 )

    Most important by a long way is Random Agent Spoofer, best way so far to minimize digital fingerprinting and online tracking… god do I fricken hate Big Data. If Modzilla break this addon I will definitely migrate to a new browser, probably Pale Moon.

    For ad and other content blocking uMatrix used with uBlock Origin can’t be beat, much better than any adBlock variant.

    Others I use:
    Ghostery
    HTTPS-Everywhere
    Flash Control
    Self Destructing Cookies
    QuickJava

    Used to use Privacy Badger but the recent release pretty much broke every site I use regularly so I kicked it to the curb.

    1. Malbay said on September 23, 2015 at 11:32 pm

      No, no. Random Agent Spoofer makes you more unique. You have your own IP address, unique (to OS and browser) canvas fingerprint and with TCP SYN analysis – simple profile/useragent rotator is pretty easy revealed.

      1. al bundy said on September 26, 2015 at 8:14 am
        Reply

        Using a VPN makes IP address irrelevant, canvas support is disabled is RAS, and a whole swag of other fingerprinting techniques are blocked / spoofed (ie Silverfox, geolocation, system info, screen info, plugins info, mime-type info, fonts detection, link/dns pre-fetching, etc).

        I don’t know what TCP SYN analysis is, could you provide a conceptual overview?

        I’m not saying that RAS is foolproof by any means, but is muddies the waters sufficiently when used through a VPN.

    Here are the ones that I would like to see survive, even though I don’t use several of them, and a few of them aren’t even signed yet. Among the addons named in each category, there is some functionality overlap, and I wouldn’t mind as long as the main functionality remains available in compatible addons.
    Userscripts: Greasemonkey, Stylish.
    UI: Classic Theme Restorer, Menu Wizard, url-addon-bar (and its alternatives)
    Blocking: ABP, µBlock, BluHell Firewall, Flashblock, RequestPolicy (Continued), Policeman, etc.
    Tabs: Tree Style Tabs, Tab Mix Plus, etc.
    Links: Text Link, Redirect Bypasser, Clean Links, CoLT
    Downloads: Open in Browser, Download Statusbar alternatives.
    Website conveniences: There are too many to mention, and some that can’t be mentioned here, but functionality like that of SkipScreen needs to remain available.

    Several of the extensions in Ghacks’ best addon list aren’t really must-haves, but the list gives a good idea of the range of functionality that might be lost from the WebExtensions changes.
